A kind of duck-rice co-production method for organic rice

Abstract

The invention discloses a method for co-cropping duck and rice to produce organic rice, and belongs to the technical field of compound planting and breeding. After drying for 1-2 days, soak the seeds in clean water for 20-28 hours. After washing, soak the seeds in 2% lime water for 36-48 hours. After washing, germinate them at 20-25°C for 12-15 hours until the seeds are white. Sow in early and mid-April, dry seedling raising method, 15-20kg per mu; keep the seedling field moist, prevent insects, weeding, rice blast and rodent damage, and the seedling age is 30-45 days. 7-10 days before transplanting, apply 1500-2000 kg of decomposed manure per mu, 45-55 kg of organic fertilizer, and cover the field with shallow water. 1-2 days before transplanting or on the day of transplanting, harrow the field and plant seedlings, 15000-25000 clumps per mu. After the rice seedlings turn green in June, the ducklings hatched for 8 to 12 days will live in the initial release area for 1 to 2 days, and then put the ducks into the rice fields, 12 to 16 ducks per mu. For the first 6-8 days, 45-50g of feed was fed every day, and then the feeding was gradually stopped to allow them to forage freely. The ducks are removed from late August to early September, and the rice can be harvested when it is yellow and ripe from early to mid-September to mid-to-late October. The method effectively improves the yield and quality of rice, makes the output-input structure of materials more reasonable, and has high value for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of compound planting and breeding, and in particular relates to a method for co-cultivating duck and rice to produce organic rice. Background technique [0002] The duck-rice co-cropping compound planting and breeding system is a compound type of natural and artificial combination of domestic duck field net-raising with rice paddy field as the substrate and rice planting as the center, making full use of ecological principles such as symbiosis and mutual benefit, ecological niche and food chain. Cultivate ecosystems. The system stimulates the growth of rice through the uninterrupted activities of ducks. Duck feces can be used as organic fertilizers. Ducks’ trampling on field weeds and predation on pests can replace the use of herbicides and insecticides, and realize raising ducks in the field , Protect the rice with ducks, and make the rice and domestic ducks cohabitate and grow. However, the duck-rice co-...

Problems solved by technology

However, the duck-rice co-cropping compound breeding system currently being carried out in various places generally lacks an adaptive technical system established based on the different growth characteristics of rice and domestic duck strains, so that the co-growth promotion of rice and domestic ducks is limited. influences
